Specification of Letters Patent.

Application led December 18, 1912. Serial N o. 737,387.

To all whomzt may concern Be it knownthat I, PHILIP T. DODGE, a citizen of the United States, residing at New York, in the county of New York and State of .New York, have invented certain new and useful Improvements in Typographical` Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My ,invention relates to typographical machines, such as linotype machines of the general organization represented in-Letters Patent of the United States to O. Mergen-y thaler, No. 436,532, wherein matrices are stored end to end in a channeled magazine, and are released therefrom by suitably actuated escapement devices. .When so released, they are conveyed to a common point and there assembled side by side in line. The composed line is then transferred to the face of a slotted mold, the moldfilled with molten metal to form a slug. or linotypey against the matrices which produce the type characters thereon, and the matrices thereafter returned by a distributing mechanism to the mazagine from which they started.

In practice, it has been found that the matrices fall onto each other' in the magazine with considerable force (particularly the large or thick matrices), and as a result thereof soon become battered and worn. In'

come these objections, and to thateend '-I' have provided` means to engage andetard the matrices in their fall. Asl a suitable means for accomplishing this purpose, I have illustrated ,a roll extending acrossl the magazine and projecting into the channels thereof, so as to engage the matrices as they drop into place.

In the accompanying drawing, I have shown my invention merely by way of example and in preferred form, and as applied to the specifickind of machine aly ready mentioned, but obviouslyI many changes and variationsymay be made therechines, such as handle type, dies, etc., without departure from its spirit; and generally speaking, I desireit to be understood that IV do not limit myself to any specific form or embodiment, exceptV in so far as such limitations are specified inthe claims.

Referring to the drawing: Figure 1 is a vertical section through the inclined magazine, the distributing mechanism, etc., of a linotype machine, having my invention applied thereto. Fig. 2 is a similar View showing a vertically disposed magazine, and my yinvention in modified form; and Fig. 3-is a transverse section on the line 3 3 vof Fig. 1.

The matrices X are stored in the channeled magazine A, whichmay be supported in the inclined position shown in Fig. 1, or in the vertical position shown in Fig. 2. The matrices are released from the magazine by the .escapement devicesJ B, operated through the reeds C, from the customary key-board mechanism, and then'pass through the face-plate D to the other assembling devices, and thence to the casting mechanism. After the cast-ing operation, the matrices are delivered to the distributing mechanism,

-rices along the bar until they drop therefrom into their respective channels in the magazine A. As thus far described, the parts and operations are or may be substantially the same as those set forth in the before-mentioned Mergenthaler patent, or as embodiedvin the commercial linotype machine. Turmng now to my improvement, in order to check or. retard the falling matrices, I

provide means, preferably in. theform of a rotatin roll, having a velocity less than that of the alling matrices, and extending trans-l verselyacrossthe magazine, and projecting through an aperture therein, so as to engage wit-h the matricesas they pass into place inl their channels. eferring to Figs. 1 and 3the roll H is mounted to turn in bearings Hl on the magazine supporting frame A1, and isl rotated by the pulley I and the band or cord J from Somevconvenient part v of the machine, such as the shaft K. The

roll I-Imay be placed in any suitable position to engage the matrices during their lfall, but I prefer to locate it mid-wa be- -tween the ends of the magazines, and a so so that when the matrices are at rest, it will turn in the space between the upper and lower ears of the contiguous ones, as shown in Fig. 2, and in such manner that normally the roll will have no eiect in urging the matrices downward. It will be apparent that by varying the speed of rotation of the roll H, 'the matrices maybe caused vto drop int-o place with substantially any force desired. v.

In place of the power-driven roll H shown in Fig. 1, I have illustrated in Fig. 2, an idle roll L mounted in any suitable manner and ysimilarly located with respect to the matrices in the magazine. This roll L also acts to check the falling matrices, although perhaps not with such precision and capa-A bility of control as` the roll H. It will of course be obvious that if desired, two such rolls H or L may be employed, one on each side of the magazine, and at opposite points thereof, or that any number may be located at various points on bothsides of the magazine, as will be suggested by convenience or the amount of retardation sought to be secured. l

- As previously stated, in

be carried into lel'ect ley-oth vices, which may vary widely from those invention may shown in the vpresent instance, both in construction and operation, andI still beA comprised within its scope. 'Such variations and modifications willreadily 'suggest' theml selves to those skilled in the art.

er forms of de-- i Having thus described my invention, its construction and-mode of operation, what I claim and desire to secure by Letters Patent ofthe United States, is as follows:

.1. In a typographical machine, the'combination of a magazine for the type or matrices, and a device located between the ends of the magazine in position to engage the edges of the type or matrices and thus retard them as they pass into place therein.

2. In a typographical machine, the combination of a magazine for the type or matrices anda rotatable roll pro3eoting into the magazine so -as to engage and retard rthe typeor matrices as they pass into place therein.

3. In a typographical machine, the combination of a magazine for the ty e or matrices and a constantly rotating rol projecting into the' maga-zine so as to engage and retard vthe type .or matrices as they pass t0 PHILIP T.. DODGE.
